Fathi E. Abd El-Samie received the BSc(Honors), MSc, and PhD degrees from Menoufia University, Menouf, Egypt, in 1998, 2001, and 2005, respectively. Since 2005, he has been a teaching staff member with the Department of Electronics and Electrical Communications, Faculty of Electronic Engineering, Menoufia University. He is currently a researcher at KACST-TIC in Radio Frequency and Photonics for the e-Society (RFTONICs). He is a co-author of about 200 papers in international conference proceedings and journals and four textbooks. His current research interests include image enhancement, image restoration, image interpolation, superresolution reconstruction of images, data hiding, multimedia communications, medical image processing, optical signal processing, and digital communications.Dr. Abd El-Samie was a recipient of the Most Cited Paper Award from the Digital Signal Processing journal in 2008. Hossam Eldin H. Ahmed received a BSC(Honors) in nuclear engineering in June 1969 (Faculty of Engineering, Alexandria University, Egypt); an MSc in microelectronic electron diffraction in April 1977 (Nuclear Department, Faculty of Engineering, Alexandria University); and a PhD in June 1983 (High Institute of Electronic and Optics, Paul Sabatier University, Toulouse, France). From 1970 to 1977, he was in the Egyptian marine forces. He was a demonstrator in 1977, teaching lectures and staff members with the Department of Electronic and Electrical Communications, Faculty of Engineering and Technology, Menoufia University. In 1993, he became a professor of microelectronics, VLSI design technology, communication systems, and computer networks. From 1993 until 1999, he was vice dean for education and student affairs at the Faculty of Electronic Engineering. In 2001, he became a chairman of the Electronics and Electrical Communications Department. He is a member of the Menoufia periodic electronic faculty jou

Investigating image encryption approaches, this book examines image encryption algorithms for the purpose of wireless communication of images in secure form. It considers two directions for image encryption: permutation-based encryption and diffusion-based encryption. Covering the range of image encryption principles and techniques, it presents hybrid encryption algorithms to enhance the characteristics of traditional algorithms. It explores number theory-based encryption algorithms, details the strength of different encryption algorithms, and describes their ability to work within the limitations of wireless communication systems.
